Antennas are transducers that transfer electromagnetic energy between a transmission line and free space. Antennas are in general reciprocal devices, which can be used both as transmitting and as receiving elements. This is how the antennas on cellular phones and walkie−talkies operate. The basic principle of operation of an antenna is easily understood starting from a two−wire transmission line, terminated by an open circuit. |
